Sec 4 G3 Combined Science (Chem, Bio) Tuition
Ancourage Academy · Secondary · Sec 4
Content reviewed: Jul 2026
Secondary 4 (Sec 4) Combined Science (Chemistry/Biology), commonly called Combi Sci, tuition at Ancourage Academy in Singapore (Bishan & Woodlands) offers small groups of 3-6 learners, following Singapore's MOE syllabus. Weekly 2-hour lessons use our ESB methodology to build conceptual mastery, practical skills, and exam readiness for O-Level success. "Curiosity drives scientific discovery—we channel it through guided inquiry and hands-on exploration," according to our educators. Our structured approach helps students perform confidently across Paper 1, 2, and 3.

What Makes Us Different
Our proven teaching methodology combines evidence-based approaches for maximum learning effectiveness
Ebbinghaus Memory Theory
Student-managed revision within the relevant science discipline or subject pair — identifying weak topics through past-paper analysis and scheduling retrieval cycles accordingly — developing the self-assessment skills the O-Level / SEC science papers demand.
Socratic Questioning
Rigorous questioning on experimental design and data interpretation — 'What are the limitations of this method?' and 'How does this finding challenge the accepted model?' — cultivating the analytical depth expected in higher-level science.
Bruner's Scaffolding
Minimal guidance on open-ended problems — tutors present unfamiliar experimental scenarios and observe, intervening only to correct fundamental misconceptions — preparing students for the independent investigation demands of advanced science.

Key Transition
The final upper secondary year requires integrating knowledge from both disciplines — students must demonstrate comprehensive understanding under exam conditions.
“Combined Science pairs two of Physics, Chemistry and Biology — students are assessed in both components, so they must be competent across the pair without the depth of pure science. We help students identify the high-yield topics in each component and develop efficient revision strategies that maximise marks across all sections.”

Frequently Asked Questions
We cover all exam components: Paper 1 (MCQ), Paper 3 (Structured, Chemistry), Paper 4 (Structured, Biology), and Paper 5 (Practical). Students develop strategies for both chemistry and biology sections, focusing on scientific keywords, diagram accuracy, and efficient time management.
We recommend identifying weaker areas first and allocating more time accordingly. Chemistry often requires more equation practice while Biology needs diagram and process memorisation. Our lessons help students develop subject-specific study strategies. Read our Pure vs Combined Science comparison.
Combined Science (Chem/Bio) suits students pursuing non-science intensive pathways like business, humanities, social sciences, or certain healthcare support roles. For medicine, nursing, or life sciences, Pure Sciences are typically required.
We combine topical mastery with timed practice papers, exam technique coaching, and detailed feedback. Our small groups of 3-6 ensure each student gets individual attention on their weakest areas, with targeted revision and error pattern analysis to maximise improvement before the exam. For SEC Combined Science (K328, formerly 5088), our classes provide step-by-step support through Chemistry bonding concepts and Biology diagrams. Learn more in our secondary Science tuition guide.
Sec 4 Combined Science (Chemistry/Biology) sessions run weekly for 2 hours at our Bishan and Woodlands centres. Our 3-6 student classes allow personalised revision of the 5088 O-Level / SEC paper in this critical final year. See our pricing page for fees, or start with a trial class — free (usually $18).
Our Bishan centre is 10 minutes on foot from Bishan MRT (NS17/CC15, North-South and Circle Lines). Our Woodlands centre at Vista Point is 5 minutes from Woodlands South MRT (TE3, Thomson-East Coast Line). Sec 4 students from Whitley Secondary, Guangyang Secondary, Kuo Chuan Presbyterian Secondary and Marsiling Secondary, Woodlands Ring Secondary, Woodgrove Secondary attend regularly.
Our small-group classes are intentionally kept between 3 and 6 students so every learner receives close guidance, timely feedback, and ample practice.
Each lesson is 2 hours, providing ample time for thorough coverage of topics and interactive learning.
Yes. All lesson materials and worksheets are provided and included in the fees. Students should bring regular stationery and, where applicable, school textbooks/workbooks for reference.
Yes. Our materials and pacing align with the MOE syllabus. External syllabuses (e.g. IGCSE, IB) are available upon request.
This course covers G3 (mapped from Express standard) Combined Science Chem Bio under Singapore's Full Subject-Based Banding (Full SBB). We also support students at other G-levels. Contact us to discuss your child's current G-level and the best class arrangement.
